Config usage example

var config = new StandaloneClientConfigurationBuilder()
    .WithAddress("localhost", 6379)
    .WithAddress("hoho", 8080)
    .WithAddress("asdf")
    .WithAuthentication(null, "pwd")
    .With(ProtocolVersion.RESP3)
    .With(TlsMode.SecureTls)
    .WithRequestTimeout(23400)
    .With(ReadFrom.PreferReplica)
    .WithDataBaseId(42)
    .WithConnectionRetryStrategy(1, 2, 3)
    .WithClientName("pewpew")
    .Build();

Config extended samples

var builder = new StandaloneClientConfigurationBuilder();
builder
    .WithAddress(("server", 42))
    .WithAddress("server", 42)

    .WithAddress("server", null)
    .WithAddress(42)
    .WithAddress(port: 42)
    .WithAddress("server")
    .WithAddress(("server", null))
    .WithAddress((host: "server", port: 42))
  //.WithAddress((port: 42, host: "server")) - doesn't work
    .WithAddress(port: 42, host: "server")
    .WithAddress(port: 42)
    .WithAddress(host: "server")
    ;
builder.Addresses += ("server", 42);
builder.Addresses += (host: "server", port: 42);
//builder.Addresses += (port: 42, host: "server"); - doesn't work
builder.Addresses += ("server", null);
builder.Addresses += (null, (uint?)42);

this stuff is not thread safe, but I assume it is ok

[jonathanl-bq]

Should we have documentation for the types here?

[Yury-Fridlyand]

1:1
Will do

[Yury-Fridlyand]

Done. Do you know how to add a reference to an arbitrary file by relative path ?

[jonathanl-bq]

You mean like this? https://stackoverflow.com/questions/7653483/github-relative-link-in-markdown-file

[Yury-Fridlyand]

I can't understand where relative path starts from. I tried to point to connection_request.proto, but all experiments with ../../.. failed

[jonathanl-bq]

This approval is for the Rust portion of the code. I left some comments on documentation that needs to be updated, but otherwise, this looks fine to me.
